T6 alfwfiem it may concern:-

Be it known that I,-E'mws'r Sononowsxr, a. subject of the Emperor of Germany, re-

at Hamburg, Germany, have invent ed' a new and useful Improvement in Det-v onators for Hand-Grenades, of which thefollowing is a full, clear, and exact description, reference being had to the acying drawings, which form-a part of this specification.

The subject matterof this invention is a detonator for hand grenades, consisting of a. tube into which is rigidly placed from. one-side a pin with a small propelling charge and; behind this-a column of-a slowly with a. protecting screw cover, while from the other side a screw-is introduced to. which 7 the detonating cap is fastened shortly before.the grenade is used.

v The purpose of this invention is to render possible that the caps be carried separately from the grenades, due to the factthat in:

accordance with certain railroad regulations 1- itnotpermitted to ship caps in contact with charges exceeding 20' gr.

' I will now describe the embodiment of my. invention shown infthe accompanying drawings, in whichg Figure 1 is an elevation principally in: central section of" a hand grenade .embodying my invention. Fig, 2 is a cross'section for instance of brass, mmsthreuglrthe twoparts b" of a discus genadeprovided with suitable openings in 'such manner-thatafter these-.twoparts have The tuhe a, made been riveted together the tube is tightly surrounded by the samez Into this tuhe a the cap screw a to which. the cap dis fastened, introduced shortly before the grenade is used. v '7 Agt the lace where the-cap rests, thewalis'= of theitu e a may be: weakened so as to:

$5 facilitate the propgiglation of the detonation upon- 'the'surroun g" explosive char of the projectile. Toward the center, t e in- I side diameter of the hereof the-tube :a; be-

comes narrow, expanding in the direction of. the other s1'de.' This part serves for the.

purpose of receiving the pin e which, by

means of a small propellingcharge f, after the strinehas beenignited, is driven into ='tnecap, thus detbnat'i'ng the latter. -"Qnthe ye other side" 'of't pr p charge isE thetermined' slow speed. The speed of burning of this mixture is regulated by means of pressing. For the purpose of igniting the Igniting mixture g, a short column of another igniting mixture h is provided, this latter igniting mixture being ignited in any desired manner from the. outside, after the screw cover 2', which protects same, has been. removed before the grenade is thrown.
